Short on miles, big on scenery. This 4.0-mile out-and-back visits three photogenic cirque lakes tucked beneath the north side of Reading Peak. Expect clear water, mirrored reflections, and a surprising amount of shade as you weave through forest, meadows, and shoreline. Plan on about 3 hours if you linger at the lakes; fast walkers who turn around earlier often finish in 1.5–2 hours.
Start at the signed Terrace Lake turnout on the park highway (about 9 miles from the Southwest Entrance). The trail drops immediately. At 0.2 miles, a signed junction splits left to Hat Lake and right to the lakes—go right. One-way distances are roughly 0.5 mile to Terrace, 0.8 mile to Shadow, and 2.0 miles to Cliff. You’ll skirt Terrace and Shadow along the shore, then cross open woods and meadows, over a low moraine, to reach emerald-toned Cliff Lake.
This hike hikes easy to hard—in reverse. You descend first, then pay it back. Expect about 300 feet down to Terrace, 350 feet to Shadow, and 650 feet to Cliff, with the same climb returning to the highway. The tread is natural and occasionally rocky/rooty, with some short steep pitches. Signage is average and a few sections can feel confusing; keeping an eye on junctions helps.
Each lake has its own personality—Terrace’s grass-lined shore, Shadow’s glassy reflections, and Cliff’s striking green hues beneath rocky slopes. The basins are glacial cirques, and that low rise near Cliff is a moraine. Wildflowers often color the meadows in late summer, and you may spot tiny fish in the water. At ~8,000 feet on north-facing slopes, snow can linger later here than elsewhere in the park; early season may include snow patches.
Late summer into early fall typically offers the driest tread, fewer mosquitoes, and calmer water for reflections—mornings are best for mirrorlike surfaces. Shoulder seasons can be gorgeous but bring lingering snow and slick sections. Weekdays and early starts help with both solitude and parking.
If you want a bigger day on similar scenery, a longer approach via Summit Lake also reaches Shadow/Cliff (different trailhead and mileage), but the classic three-lake outing from the highway turnout is the most direct.
Small signed highway turnout labeled “Terrace Lake,” about 9 miles from the Southwest Entrance; roadside shoulder parking with no formal lot or services.
Immediate steep descent on rocky/rooty tread; north-facing, high-elevation slopes hold snow late; thunderstorms and mosquitoes are possible; average signage with a key fork at 0.2 mi; cold water; expect ~650–700 ft climb back to the car.
